Grating Spectroscope [2434]

Grating Spectroscope. Plastic, direct vision student spectroscope, fitted with a high efficiency grating in the eyepiece which produces a brilliant spectrum even in poor light. The adjustable slit permits maximum resolution and the sharpest bands at predominant wavelengths, viewed directly against a scale graduated in nanometres. The outer surface of the calorimeter has the wavelength of some commonly found spectra. Dimensions 195mm x 98mm x 25mm.
